Question

in triangle ABC if angle B is 76 degree and angle C is 48 degree. Find angle A

Answer 1

Answer: 56°

In ∆ABC,

Angle A + Angle B + Angle C = 180° (Angle Sum Property)

Angle A + 76° + 48° = 180°

Angle A + 124° = 180°

Angle A = 180° -124°

= 56°

Answer 2

Answer:

The answer to the given question is angle A is 56°.

Step-by-step explanation:

Given :

Triangle ABC

angle B = 76°.

angle C = 48°

To find :

angle A?

Solution :

In a triangle ABC,

The Sum of all the angles of a triangle is equal to 180°.

angle A+angle B+ angle C = 180°.

On adding the given three angles we get the value of 180°.

It is given that angle B = 76° and angle C = 48°.

let the angle A be x.

On substituting the given values in the above data, we get the values as

$x + 76 + 48 = 180$

on further simplification, we get the values as

$124 + x = 180$

The value adding the x on the left side subtracts the value on the right side.

$x = 180 - 124 \\ x = 56$

The value of x is found as 56.

Therefore, the final answer to the given question is angle A is 56°.
